The diopter adjustment lever 120 is arranged on the lower surface side of the eyepiece section 28 when viewed from the eyepiece window 22 side, and is slidably fitted into the finder guide tube 43.

The surface of the finder guide tube 43 into which the diopter adjustment lever 120 is slidably fitted is adjacent to the surface on which the locking claw 43c is provided.

That is, the respective positional relationships are described with the finder lens as the center when viewed from the eyepiece window 22 side.

A lens holder biasing spring 146 is provided at the upper right corner of the lens holder 42, a guide shaft 44 is provided at the upper left corner of the finder guide tube 43, and locking claws 43c are provided at the lower left and right sides of the finder guide tube 43.

Here, as described in FIG. 4A, when the finder unit 21 is housed in the imaging device 1 when viewed from the eyepiece window 22 side, the lens barrel unit is located at the lower right side of the eyepiece section 28. 2 is placed in this relationship.

Furthermore, as explained in FIG. 3(c), the finder fixing cylinder 45 is optimally located on the diagonal side with respect to the finder unit rotating shaft 50.

Therefore, the locking means for restricting the rotation of the finder rotating section 41 shown in FIG. Deploy.

As a result, the finder rotating section 41 can be reliably locked without increasing the size of the imaging device 1 and without transitioning to an unexpected state.

(Explanation of regulation of rotational movement of electronic viewfinder unit 21)
Next, with reference to FIG. 5, the regulation of the rotational movement of the electronic viewfinder unit 21 after the electronic viewfinder unit 21 is in the protruding state will be described.

FIG. 5 shows the electronic viewfinder unit 21 with the eyepiece 28 in the retracted state.

In FIG. 5A, a grip portion 157 is a portion that is gripped to pull out the eyepiece portion 28. Therefore, the grip portion 157 is partially thicker than other portions of the eyepiece portion 28.

The regulating shape portion 153 is provided integrally with the eyepiece portion 28 . The regulating shape portion 153 is thinner than the gripping portion 157. The rotation locking member 130 is located inside the regulating shape portion 153 when the eyepiece portion 28 is in the stored state.

FIG. 5(b) is a cross section perpendicular to the finder optical axis of FIG. 5(a).

In a cross section perpendicular to the rotating shaft 131 , the rotation locking member 130 has a locking contact surface 154 , a guiding surface 155 , and a rotation restriction surface 156 .

The locking contact surface 154 is in contact with a locking portion 145 provided on the fixed cylinder 45. Therefore, the finder rotating section 41 constituting the finder unit 21 is locked in a state parallel to the finder lens optical axis and the imaging lens (not shown).

When the eyepiece 28 is in the retracted state, the rotation locking member 130 is located inside the regulation shaped portion 153 provided on the eyepiece 28 .

Therefore, even if the rotation locking member 130 attempts to rotate against the urging force of the urging spring 132, the rotation is restricted due to the interference of the rotation restriction surface 156 with the restriction shape portion 153. There is.

That is, when the eyepiece section 28 is in the retracted state, the fixed barrel 45 is not released from the locked state and cannot be rotated.

When viewed from the surface 49a of the finder cover 49 as a holding cover, the intersection P between the guiding surface 155 as a tapered surface and the rotation regulating surface 156 is within the projection of the grip portion 157.

The grip portion 157 is a thick portion to ensure strength. Therefore, even if the rotation regulating surface 156 interferes with the regulating shape portion 153, the regulating shape portion 153 will not be elastically deformed.

Therefore, when the eyepiece section 28 is in the retracted state, the fixed tube 45 is securely locked, and the finder rotating section 41 will not be inadvertently rotated and its state will not change.

(Description of rotation locking member 130)
FIG. 6A shows the finder unit 21 with the eyepiece 28 pulled out to the use position.

FIG. 6(b) is a cross section perpendicular to the finder optical axis of FIG. 6(a).

FIG. 6(c) shows a state in which the rotating portion 41 starts rotating from the state in which the eyepiece portion 28 shown in FIG. 6(a) is pulled out to the use position.

FIG. 6(d) is a cross section perpendicular to the optical axis direction G of the photographing lens of the imaging device 1 of FIG. 6(c).

In FIG. 6(a), the regulation shape part 153 provided integrally with the eyepiece part 28 has a notch shape 158 provided in an extending part of the eyepiece part 28 in the direction of the finder optical axis.

When the eyepiece 28 is pulled out to the use position, the rotation regulating surface 156 is exposed from the eyepiece 28 because of the cutout shape 158.

Therefore, the rotation restriction surface 156 provided on the rotation locking member 130 is prevented from interfering with the restriction shape portion 153.

Next, FIG. 6(c) shows a state in which the rotation locking member 130 has started rotating. The locking contact surface 154 is pushed in the opposite direction to the urging direction by the locking portion 145 provided on the fixed cylinder 45 and rotates.

Because of the notch shape 158, when the rotation locking member 130 starts to rotate, the rotation restriction surface 156 is prevented from interfering with the restriction shape portion 153.

Therefore, the rotation locking member 130 is rotatable against the biasing force of the biasing spring 132.

6(d) is a cross section of FIG. 6(c) perpendicular to the optical axis direction G of the photographing lens of the imaging device 1. FIG.

As shown in FIG. 6(d), as the fixed cylinder 45 rotates, the rotation locking member 130 rotates about the rotation locking shaft 131.

The intersection point P between the guiding surface 155 as a tapered surface and the rotation restriction surface 156 moves to the outside of the outermost shape of the eyepiece section 28 .

Therefore, the locking contact surface 154 of the rotation locking member 130 is separated from the locking portion 145 provided on the fixed cylinder 45, and the locking is released.

In other words, the fixed cylinder 45 can be rotated up to a predetermined angle.

FIG. 6(e) shows a cross section of the finder unit 21 perpendicular to the finder optical axis during the transition from the state in which the fixed barrel 45 is rotated by a predetermined angle to the stored state at 0 degrees.

The rotation locking member 130 is biased by the biasing force of a biasing spring 132.

When the fixed cylinder 45 transitions from a state in which it has been rotated by a predetermined angle to a stored state at 0 degrees, the guiding surface 155 comes into contact with the locking part 145, as shown in FIG. 6(e).

Due to the locking portion 145 of the guiding surface 155, the rotation locking member 130 rotates about the rotation locking shaft 131 in a direction opposite to the urging direction.

That is, the locking portion 145 rotates the rotation locking member 130.

The guiding surface 155 as a tapered surface returns to the state shown in FIG. 6(c) while contacting the locking portion 145.

Therefore, the electronic viewfinder unit 21 transitions from a state in which it has been rotated by a predetermined angle to a stored state at 0 degrees, and is locked again.

The locking contact surface 154, the guiding surface 155, and the rotation restriction surface 156 are adjacent to each other. Therefore, the rotation locking member 130 can be made smaller. As a result, the rotation locking member 130 can lock the fixed cylinder 45 inside the finder cover 49.

Therefore, in the state where the finder unit 21 is protruded, the eyepiece section 28 is pulled out and put into use, so that the finder unit 21 becomes rotatable.

Furthermore, when the eyepiece 28 is in the retracted state, the rotation locking member 130 is restricted from being easily rotated by the restriction shaped portion 153 provided on the eyepiece 28, and the finder rotation portion 41 may be inadvertently moved. It becomes possible to suppress state transitions.

Consider a case where the electronic viewfinder unit 21 is viewed from the eyepiece window 22 side in a state of protruding from the main body.

The rotation of the rotation unit 41 is locked on the side opposite to the rotation axis 50 of the rotation unit 41 around the optical axis of the finder lens, and on the opposite side to the lens barrel unit 2 around the optical axis of the finder lens. A rotation locking member 130 is arranged.

Further, the rotation unit 41 includes a detection sensor for switching the display on the display unit 15 of the imaging device 1, and a sensor window 23 provided in the optical path of the detection sensor.

When viewed from the eyepiece window 22 side, the sensor window 23 is arranged on the rotation axis 50 side of the rotation unit 41 with the eyepiece window 22 as the center in the translational direction of the electronic viewfinder unit 21 .

The diopter adjustment lever 120 is arranged on the opposite side to the rotation axis 50 of the rotation unit 41 with the eyepiece window 22 as the center in the translation direction of the electronic viewfinder unit 21 .

The rotation unit 41 includes a fixed barrel 45 that accommodates a guide barrel 43 so as to be movable in a direct manner on the optical axis of the finder lens.

The eyepiece 28 is engaged with the guide tube 43 and moves in translation together with the guide tube 43 in the optical axis direction of the finder lens.

Consider the case viewed from the eyepiece window 22 side.

The guide tube 43 includes a guide shaft 44 that guides the lens holder 42 toward the rotation axis of the rotation unit 41 around the eyepiece window 22 in the translational direction of the electronic viewfinder unit 21, and a biasing spring 146 that biases the lens holder 42. is provided.

When viewed from the eyepiece window 22 side, the guide tube 43 has a plurality of holes connected to the eyepiece section 28 on the side opposite to the rotation axis 50 of the rotation unit 21 with the eyepiece window 22 as the center in the translational direction of the electronic viewfinder unit 21. A locking claw 43c is provided.

The holding cover 49 includes two surfaces 49a in which flat plates extend in directions parallel to the optical axis direction G of the photographing optical system and parallel to the movable direction in the retracted state and the protruded state with respect to the main body of the imaging device 1. ing.

The rotation unit 41 is rotatably supported within the holding cover by a rotating shaft 50 of the rotation unit 41 in the protruding state.

When viewed from a direction perpendicular to the surface 49a of the holding cover 49, the rotation locking member 130 is disposed on the diagonal side of the rotation shaft 50 of the rotation unit 21 with the fixed cylinder 45 as the center.

The fixed cylinder 45 is provided with a locking portion 145 that engages with the rotation locking member 130 .

Furthermore, it includes a substrate 60 fixed to the fixing member 32 together with the holding cover 49,
The rotation locking member 130 is pivotally supported by the substrate 60, and the rotation locking member 130 is rotatable about a rotation axis extending in the optical axis direction of the finder lens.

The rotation locking member 130 is urged by a biasing spring 132 toward the side that comes into contact with the locking portion 145 .

When viewed from the eyepiece window 22 side, the rotation locking member 130 is located at a position closer to the optical axis of the finder lens than the surface 49a of the holding cover 49 when the locking portion 145 of the fixed tube 45 is locked. It is located in

The rotation locking member 130 prevents the electronic viewfinder unit 21 from moving to the stored state with respect to the main body 1 when the rotation unit 41 is rotating.

The rotation locking member 130 is pivotally supported by a fixing member 32 to which the holding cover 49 is fixed by a rotation locking shaft 131 extending in the optical axis direction of the finder lens.

The rotation locking member 130 is biased by a biasing spring 132.

The rotation locking member 130 moves to a restriction position that restricts movement of the electronic viewfinder unit 21 to the stored state in the rotation direction of the rotation unit 41.

Thereafter, the rotation locking member 130 is rotatable in the order of a locking position where the rotational movement of the rotational unit 41 is locked and a release position where the rotational movement of the rotational unit 41 is unlocked.

In the restricted position, an abutting portion 137 that engages with the main body portion 1 is formed at one end of the rotation locking member 130 .

The other end of the rotation locking member 130 is provided with an abutment surface 154 that locks on the rotation unit 41 and restricts the rotation movement.

When viewed from the eyepiece window side, the abutment surface 154 and the abutting portion 137 are formed on opposite sides with the rotation locking shaft 131 interposed therebetween.

The rotation restricting portion having the abutting surface 154 at one end of the rotation locking member 130 has a tapered surface 155 for returning the rotation unit 41 from the rotating state to the locking position.

(Explanation of slide prevention mechanism)
Next, with reference to FIG. 7, a mechanism for preventing the electronic viewfinder unit 21 from sliding to the stored position during rotational operation will be described.

FIG. 7A is a cross-sectional view showing the configuration of the rotation locking member 130 in a state where the finder rotation portion 41 is rotated.

FIG. 7(b) is an enlarged view showing the details of the rotation locking member 130.

In FIG. 7A, the finder rotating part 41 is shown rotated 90 degrees as shown in FIG. It is rotated by the biasing spring 132 and stopped in a state in which it is in contact with the substrate base 60.

The upper part of the rotation locking member 130 shown in FIG. A main body storage abutting portion 137 is formed on the opposite side.

In FIG. 7, the rotation locking member 130 is biased from the locking position (the state shown in FIG. 5(b)) where the rotation movement of the finder unit 21 is restricted.

Therefore, it is rotated further to the overstroke position.

At this time, the main body storage abutting part 137 provided on a part of the rotation locking member 130 also rotates further from the locking position (the state shown in FIG. 5(b)) and rotates to the outside of the locking position. It's stopped.

As explained with reference to FIG. 3(a), the spring holder 35 is fixed to the EVF holder 30 described above (shown in FIG. 3(a)).

The abutment portion 35a is provided on the spring holder 35 so as to face the main body storage abutment portion 137 when the rotation locking member 130 is stopped at the overstroke position.

As a result, the finder unit 21 attempts to move to the stored state with respect to the imaging device main body 1 in the rotating state.

In that case, the main body storage abutment portion 137 abuts against the abutment portion 35a of the spring holder 35, thereby preventing sliding movement to the storage state.

In this manner, the rotation locking member 130 is biased from the locking position and rotates to the overstroke position.

Then, the main body storage abutment portion 137 abuts against the abutment portion 35a of the spring holder 35, thereby preventing sliding movement to the storage state.

The rotation locking member 130 is a single member that locks the rotation of the fixed cylinder 45, thereby suppressing the rotation of the finder unit 21 and suppressing the movement of the finder unit 21 toward the stored state. It is possible.

In other words, the finder unit 21 is prevented from inadvertently transitioning to an unintended state with a small number of parts.

As a result, the problem that the finder unit 21 is inadvertently lowered toward the stored state after the rotation operation of the finder unit 21 when the camera is used, and the finder display image cannot be visually recognized, is eliminated.

As explained above, the locking contact surface 154 provided on the rotation locking member 130 is in contact with the locking portion 145 provided on the fixed cylinder 45.

When the eyepiece 28 is in the stored state, the rotation of the rotation locking member 130 is such that the rotation restriction surface 156 provided on the rotation locking member 130 is regulated by the restriction shaped portion 153 provided on the eyepiece 28 . has been done.

Therefore, the finder rotating section 41 constituting the finder unit 21 is locked in a state parallel to the finder lens optical axis and the imaging lens (not shown).

Moreover, the main body storage abutment part 137 provided on the rotation locking member 130 abuts against the abutment part 35a of the spring holder 35, thereby preventing sliding movement to the storage state.

Depending on the state of the eyepiece section 28, the finder 20 can prevent a decrease in convenience and damage to the camera due to inadvertent transition to an unintended state.

As another embodiment, separate members may have the function of suppressing the rotational movement of the finder unit 21 and the function of suppressing movement toward the stored state.

The rotation restriction portion of the rotation locking member 130 has a rotation restriction surface 156 , and the eyepiece portion 28 has a restriction surface 153 .

When the rotation unit 41 is housed in the holding cover 49, the restriction surface 153 engages with the rotation restriction surface 156, thereby restricting rotation of the rotation unit 41.

A notch 158 is formed in the restriction surface 153, and when the eyepiece section 28 is pulled out to the use position, the rotation restriction surface 156 of the rotation locking member 130 is cut out in the optical axis direction of the finder lens. It is located in section 158.

Therefore, the restriction surface 153 does not engage with the rotation restriction surface 156.

The rotation unit 41 includes a guide tube 43 that holds the lens holder 42, and a fixed tube 45 that accommodates the guide tube 43 so as to be movable linearly on the optical axis of the finder lens.

At the locking position where the rotational movement of the rotation unit 41 is locked, the contact surface 154 contacts a locking portion 145 provided on the fixed cylinder 45 .

The tapered surface 155 comes into contact with the locking portion 145 provided on the fixed cylinder 45 when the rotating unit 41 returns from the rotating state to the locking position.

When viewed from the eyepiece window 22 side, the tapered surface 155 and the rotation regulating surface 156 are adjacent to each other, and the tapered surface 155 and the contact surface 154 are adjacent to each other.

The holding cover 49 includes two surfaces 49a in which flat plates extend in directions parallel to the optical axis direction G of the photographing optical system and parallel to the movable direction in the retracted state and the protruded state with respect to the main body of the imaging device 1. ing.

The intersection point P formed on the extension of the adjacent tapered surface 155 and the rotation restriction surface 156 is within the projection of the thick portion of the restriction surface 153 when viewed from the surface 49a side of the holding cover 49.

A thick portion of the regulating surface 153 is a grip portion 157 that is gripped to pull out the eyepiece portion 28 .

Although preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and changes can be made within the scope of the gist thereof.
